Question

True or false the angle

Answer 1

Second option: False

Explanation:

You need to use the following identity:

`sin\alpha=(opposite)/(hypotenuse)`

Let be "x" the lenght of the buildings's shadow.

`opposite=x` (Lenght of building's shadow)

You can observe in the figure that:

`\alpha=75\°\\\\hypotenuse=50ft`

Substitute these values into
`sin\alpha=(opposite)/(hypotenuse)` and solve for ""x":

`sin(75\°)=(x)/(50)\\\\(50)(sin(75\°))=x\\\\x=48.29\°`

Therefore, the length of its shadow IS NOT 12.94 feet.
